        public <U extends T> WeldInstance<U> select​(jakarta.enterprise.util.TypeLiteral<U> subtype,
                                            Annotation... qualifiers)
        Specified by:

                                  Annotation... qualifiers)
        Description copied from interface: WeldInstance

        Obtains a child Instance for the given required type and additional required qualifiers. Must be invoked on Instance<T> where T is Object.

        Specified by:
        select in interface WeldInstance<T>
        Type Parameters:
        X - the required type
        Parameters:
        subtype - a Type representing the required type
        qualifiers - the additional required qualifiers
        Returns:
        the child Instance

      • destroy

        public void destroy​(T instance)
        Specified by:
        destroy in interface jakarta.enterprise.inject.Instance<T>

      • getHandle

        public jakarta.enterprise.inject.Instance.Handle<T> getHandle()
        Specified by:
        getHandle in interface jakarta.enterprise.inject.Instance<T>

      • getHandler

        public WeldInstance.Handler<T> getHandler()
        Description copied from interface: WeldInstance
        This method is deprecated as a similar functioning method exists in CDI 4.0 and newer. Users should instead use Instance.getHandle(). Obtains an initialized contextual reference handler for the bean that has the required type and required qualifiers and is eligible for injection.

        The contextual reference is obtained lazily, i.e. when first needed.

        Specified by:
        getHandler in interface WeldInstance<T>
        Returns:
        a new handler

      • isResolvable

        public boolean isResolvable()
        Specified by:
        isResolvable in interface jakarta.enterprise.inject.Instance<T>

      • handles

        public Iterable<jakarta.enterprise.inject.Instance.Handle<T>> handles()
        Specified by:
        handles in interface jakarta.enterprise.inject.Instance<T>

      • handlers

        public Iterable<WeldInstance.Handler<T>> handlers()
        Description copied from interface: WeldInstance
        This method is deprecated as a similar functioning method exists in CDI 4.0 and newer. Users should instead use Instance.handles(). Allows to iterate over contextual reference handlers for all the beans that have the required type and required qualifiers and are eligible for injection.

        Note that the returned Iterable is stateless and so each Iterable.iterator() produces a new set of handlers.

        Specified by:
        handlers in interface WeldInstance<T>
        Returns:
        a new iterable

      • getPriorityComparator

        public Comparator<WeldInstance.Handler<?>> getPriorityComparator()
        Description copied from interface: WeldInstance
        This method is deprecated in favor of WeldInstance.getHandlePriorityComparator() which operates on a non-deprecated Instance.Handle interface. The returned comparator sorts handlers by priority in descending order.
        • A class-based bean whose annotated type has jakarta.annotation.Priority has the priority of value jakarta.annotation.Priority#value()
        • A custom bean which implements Prioritized has the priority of value Prioritized.getPriority()
        • Any other bean has the priority of value 0
        Specified by:
        getPriorityComparator in interface WeldInstance<T>
        Returns:
        a comparator instance

      • getHandlePriorityComparator

        public Comparator<jakarta.enterprise.inject.Instance.Handle<?>> getHandlePriorityComparator()
        Description copied from interface: WeldInstance
        The returned comparator sorts handles by priority in descending order.
        • A class-based bean whose annotated type has jakarta.annotation.Priority has the priority of value jakarta.annotation.Priority#value()
        • A custom bean which implements Prioritized has the priority of value Prioritized.getPriority()
        • Any other bean has the priority of value 0
        Specified by:
        getHandlePriorityComparator in interface WeldInstance<T>
        Returns:
        a comparator instance
